OF GENERAL INTEREST: OCEAN CIRCULATION
"Modeling Ocean Circulation," A.J. Semtner (Dept. Oceanog.,
Naval Postgraduate Sch., Monterey CA 93943), Science, 269(5229),
1379-1385, Sep. 8, 1995.
An extensive review of the status of ocean numerical models, which have
become quite realistic over the past several years as a result of improved
methods, faster computers, and global data sets. Now models can represent not
only ocean currents, but also the consequences for climate, biology and
geochemistry over time spans of months to decades. However, much remains to be
understood from models about ocean circulation on longer time scales, including
the predictability of climate and the ocean's influence on global change.
"Climate and the Conveyor," G.C. Bond (Lamont-Doherty Earth
Observ., Rte. 9W, Palisades NY 10964), Nature, 377(6548),
383-384, Oct. 5, 1995.
Discusses three recent studies that support the theory that the sudden
climate jumps of the last glacial period are related to sudden changes in the
operation of the Atlantic Ocean's "conveyor belt" or deep water
circulation. These changes could have been triggered by injections of glacial
meltwater, but if they can occur independent of glacial ice, the odds of a
climate jolt in the near future might be much higher.
